Rohde & Schwarz HK309 Dipole Antenna 20 MHz – 1.3 GHz
Description
Rohde & Schwarz HK309 Passive Receiving Dipole Antenna 20 MHz – 1.3 GHz has an extremely wide bandwidth and high sensitivity that make it particularly suitable for reception tasks in communications, reconnaissance and measurement.
Compact design, a minimum number of distribution and switching units and a high S/N ratio are essential features for these applications. The broadband characteristic of the passive receiving dipole is ensured by eight impedance elements which suppress nulls in the main direction of reception.
Features
- Extremely wide frequency range
- High sensitivity
- High large-signal immunity
- High protection against lightning strokes in the vicinity
- Small dimensions (dipole length only 1.7 m)
- Low weight
